Vision for Proactive Climate Change Adaptation in the Danish Water Sector
Speaker: Helle Katrine Andersen, DANVA hka@danva.dk
To inspire water utilities to develop climate change adaptation strategies and to implement
CC adaptation solutions The Danish Water and Waste Water Association (DANVA) has
developed a vision for Proactive Climate Change Adaptation in the Water Sector

Uncertainty 3 – (partial) remedies
• Retrospective and prospective approaches
• (statistical) sensitivity analysis (data; parameters)
• error propagation analysis (how deviations develop in a model)
• benchmarking (accuracy compared to other models

The observed travel time differences already mentioned can either be obtained from absolute times of
measured (picked) phase arrivals (logged in earthquake catalogs) or as relative times between phases
measured with cross-correlation (CC) of waveforms. CC between closely spaced earthquakes can give
highly accurate relative time differences between phases, and can correct bad picks from

side.

movements; grey: auxiliary services that strongly interact with effects of CC.

technological development, 5) equitable distribution of social goods, ethical dynamics
Background information and knowledge gaps: 1) time scale-what is the consensus view
of when are the CC impacts projected to begin to be felt, 2) spatial scale-where are the
impacts expected to occur, 3) vulnerability assessments of differential capacity to adapt
to CC impacts
